Preheat your oven to 350 degrees F and line a baking sheet or sheet pan with parchment paper for easier cleanup. Slice the loaf of crusty Italian bread in half horizontally and place both halves on the prepared baking sheet.
In a small bowl, combine the melted butter, minced fresh garlic, and Italian dressing until well blended into a flavorful butter mixture.
Spread the mixture evenly over the top of the bread.
In another bowl, combine the parmesan cheese, gouda, and mozzarella cheese to create the perfect cheese mixture.
Generously cover each bread half with the cheese blend. Bake for 10 minutes, then increase the oven temperature to 450 degrees F.
Continue baking for 5-8 minutes, watching closely, until the cheese becomes golden brown, bubbly, and irresistible. Sprinkle with chopped parsley, transfer to a cutting board, slice, and serve warm.
